Sncrowave 350 lx, problem is only with AC, DC works fine. Welding aluminum with green band tungsten. Settings are TIG, remote control, HF continuous, and AC. No matter how low amperage is set at on machine, barely pressing the foot petal makes it arc off and blow holes in 1/8" plate. Welding gas is argon set around 40
Voltage control failure
have a technician test to find the fault
But it works fine on DC welding stainless. Could it still be voltage control?

SOURCE: I have a miller microwave 200. what settings
I think you mean you have a Miller Synchrowave 200.
Typically, you would want to use AC below about 250 amps. In this case (to keep it simple), use AC, adjust your balance to about 4, use an 1/8" pure tungsten, pure argon at about 20CFh, and set the panel at 170amps to get things started. For general purpose, use 4043 filler.
Now - these are just generic settings, but they will get you going.

Wow you have a lot of variables here. Let's go over some of them.1.AC current 2.100%argon shield gas 3.Check your Tungsten, it must be the recommended 1or 2% and the right size, clean and the tip rounded by meting 4. High freq. turned to continous-not just "START"
5. CLEAN,CLEAN,CLEAN your Alum. with a S.S. brush that has touched NOTHING else in in it's life!
Start here and GOOD luck

Have you got the TIG torch and earth lead pluged in the wrong way around ? Should the torch be negative and earth positive ?
SOURCE: When welding with our Lincoln
replace the pedal only for there is a rheostat built into the pedal as well that has shorted out

Hello; Make sure AC Auto Balancing is Enabled; And when Welding Aluminum Aways use 100% Pure Green Coded Tugsten.Make Sure you dont have 75/25 or possibly if you know for sure your frequency balancing on your machine is working you could possibly have a bad bottle of gas try the bottle of gas on the machine that you say that runs good if it runs good put it back on the 225 if the problems still exist there is something wrong with your machine`s Ac high freqency Auto Balancing.Make sure all connections are good,check tig head for loose connections. Step Up to A 1/8 size tugsten it will carry more heat and gets less contanimated.Every time you stick your tugsten it will run contanimated untill you burn it off or clean it ,if you stick you tugsten go ahead and put a clean piece back in the tig head, Contanimated tugsten wil run dirty for 5 to 20 minutes Untill you BURN it Back Clean !?

No mxtra, I meant syncrowave 350 lx like I said.
